MULTICLGR-PRINTNG PRESS.

Application filedy January 30, 19H. Serial No. 605,478

To @il wiom it may concern:

Be it known that I, ROBERT Mnsnnn, a

citizen 'of'. the United States, residing at Chicago, in the county otCook and State ot lillinois, have inventedl certain nevv and use-- inllImprovements in Multicolor-Printing Presses, ofwhich lthe following is atali, fet-ear, and exact spcclfcation.

This 'invention' relates to improvements-in printing presses for prmtlngt-Wo or more colors upon the saine side of the same sheet, and hasespecial referencet'o presses of this class employing one ormore'transter Vcylindersdocated between adjacent impression cylindersfor causing the sheet after it'has received the impression of onecylinder, to be properly transferred to the next cylinder,

and the improvements have especial retnovelty which will now bedescribed With" reference to the accompanying draivings,

and then more particularly pointed ont in the claims.

In the said drawings, Figure 1 is ai hide elevation of the gearl sideiota multicolor printing press embodying vthis invention.

2 is a plan section of the gearing theresi, taken on an enlargedsection. Fig. 3 is a detail perspective view of one ot the' gears. Y

The invention is shown as applied to a two-color two revolution printingpress, but it will nevertheless be understood that the number ofprinting couples or printing cylinders employed above two will beimmaterial. so far as theinvention is concerned. Tin thisexemplitication of the invention, 1 is the first cylinder. 2 the secondcylinder, 'and 3 the transfer cylinder situated between cylinders 1 and2 in the usual or any suitable manner. The cylinders 1 and 2 areprovided With shafts 4, 5 respectively, mounted in suitable boxes 6, 7,in any appropriate Way, and secured to these shafts 4, 5 are gear Wheels8, 9 respectively, by meansgof Specification of Letters iatent. i

and pitch 'of the gear 10, thus making each of these gears 9, 10 what isknown as split gears. rThese gear rings 1li, 15 may be held'V securelyin place against the faces ot their respective companions by anysuitable means permitting of their rotarial or concentric adjustment.For this purpose, the Xpedient better illustrated in detail in Fig. 3 isresorted to. Thisconsists in slotting` one4 vot' the members, preferablythe gear ring vas shown 'at 16, with a Slot concentric With the centerof the gear, and providing. the main as illustrated AWith respect to thegear 10,

but in both cases it serves as a means lot firmly clamping the ring gearin place with capability of'having its teeth adjusted with relation tothe teeth et the main gear 9, or

By referring to Fig. 2 of the drawings,

it Will be seen" that the gear 9 and its ring i 10 and itsring 15.Consequently it will be seen that the ring 142 -may be utilized as a*means for taking up back-lash between lthe gears 9 andlO, While thering 15 may be utilized for a Isimilar purpose 'with rrespect to the1gear's and-'10.
